I have to disagree with Jayrome on some things. Definitely service at 5,000km. Check if the timing belt was done at 100k km. That is a MUST DO item. It is also good to do the waterpump at the same time if it has not been done. Those 2 are Pain In The ***** jobs. You would only choose 98 octane if you had noticable pinging. 195/50R15 tyres on 15x6.5 rims is what I'd choose. You can go to 16s or 17s with the right width and offset without much penalty. Agree on the paper cones, though. The front two 4" speakers that are in the dash are probably totally shagged by now. Mine were missing the entire large cone. Also, it is simply not worth doing performance mods on this car. Big brake upgrades, swaybars, extractors. Not worth it. Just buy an SX if you want to do that. It can be fun and a good learning process, but not WORTH it. If you have no speakers in the back, I believe you can fit some 5x7's in teh stock spots above the rear struts. Some models have speakers there and some don't. The ones that do have the mesh to cover the speakers with.
